Effects of cytotoxic T-lymphocyte-associated protein 4 compared to TNF inhibitors on lipid profile: Results from an observational multicentre rheumatoid arthritis cohort

Aim: To evaluate the impact of selective cytotoxic T-lymphocyte-associated protein 4 (CTLA-4Ig) compared to tumor necrosis factor inhibitors (TNFi) on cardiovascular (CV) clinical and laboratory outcomes in patients with rheumatoid arthritis (RA).Methods: We performed a prospective observational multicenter study of RA patients included in the "Cardiovascular Obesity and Rheumatic DISease (CORDIS)" Study Group database, collecting demographic, clinical, and laboratory data of those starting a CTLA-4Ig or TNFi at baseline, 6-month, and 12-month follow-up.Results: Of the 206 RA patients without previous CV events enrolled in the study, 64 received a CTLA-4Ig and 142 a TNFi. The two groups did not differ in age, gender, or smoking habits, and the prevalence of hypertension, diabetes, and metabolic syndrome was similar. Over a follow-up period of 12 months, although no significant differences were found in the disease activity course, we observed that LDL cholesterol levels slightly decreased only in the CTLA-4Ig-treated patients.Conclusions: Patients treated with both CTLA-4Ig and TNFi did not differ in disease activity response and changes in traditional CV risk factors after 12 months of treatment. However, CTL-A-4Ig treatment is associated with a favorable change in lipid profile at 12-month follow-up.
